DESCRIPTION

CFM41S120 is a 40-watt AC-DC power supply module designed to convert universal AC input (90–264 Vac) to a regulated 12V DC output with a maximum current of 3.34A. The module features high efficiency of up to 90% at full load and operates in a compact 2"×2" open-frame form factor, making it suitable for space-constrained applications. It incorporates comprehensive protection mechanisms including continuous short-circuit protection, over-voltage protection via TVS clamping at 15V, and maintains excellent voltage regulation with ±1% accuracy, ±0.5% line regulation, and ±1% load regulation. The output ripple and noise is specified at 120 mV with a 20 MHz bandwidth, and the module supports a maximum load capacitance of 3330 µF. With Class II safety certification, IEC/EN/UL 62368-1 approval, and compliance with EN55032 and FCC Class B EMC standards, the CFM41S120 is ideal for industrial control systems, telecommunications equipment, and consumer electronics requiring reliable, regulated 12V power.
